PowerUrus 14.6V 30A E8 LiFePO4 Battery Charger Features and Specifications

The PowerUrus E8 charger is well-designed, relatively compact, and lightweight, measuring just 7.3 x 3.9 x 2.8 inches (18.6 x 10 x 7 cm) and weighing ~5 pounds (~2.3 kg).

The charger is equipped with a durable aluminum casing that enhances its durability and longevity. It also features a comfortable carrying handle, which makes it portable and convenient for various applications, whether in a workshop or for outdoor use.

With an AC input voltage range of 100-240 VAC, this charger is versatile and suitable for use in many different countries and settings. It supports a DC output voltage of 14.6V, a maximum charging current of 30 Amps, and can deliver up to 420W of power.

The unit includes a cooling fan, which, in combination with the cooling fins, is rather efficient in maintaining optimal operating temperature, thus preventing overheating and potentially extending the life of both the charger and the battery.

The standard operating temperature is between -4°F and 104°F (-20°C and +40°C). The unit may operate up to 149°F (+65°C) with reduced performances.

Note: personally, when charging lithium batteries, charge them at room temperature - this helps prolong their lifetime (and the lifetime of chargers) significantly.

The charger is designed with multiple safety features to protect against overload, over-voltage, short-circuit, and reverse polarity connections. These safety measures ensure that the charger operates reliably and safely under various conditions.

AC cables are 3m long, while DC cables are 1.5m long - this gives opportunity to the user to place the charger in a well-ventilated and hopefully cool area when charging the batteries.

One of the very important features of the PowerUrus E8 is its user-friendliness - it is very easy to use, with a charging indicator showing the current status of the charging process.

Note: Although the charger is very easy to use, when the unit arrives, be sure to read the manual, and to get accustomed to your new device - after all, it is able to provide 30 Amps which is not something to play with...

The following chart lists signal LED signal codes and their meaning.

PowerUrus 14.6V 30A E8 LiFePO4 Battery Charger LED Indicator Status

LED Indicator Charger Status
LED solid Green. The charger is ready to charge, or charging is complete.
LED Green blinking. The charger is charging the battery.
Red light blinking quickly. Input voltage is under-voltage or over-voltage.
LED Red-Green or Red-Red-Green blinking alternately. The output is short-circuited, or +/- pole in reversed connections.
Red LED blinks 2 times, 1 second interval, blinks 2 times again. Charger temperature overheating alarm; recovers after cooling.
Red LED blinks 3 times, 1 second interval, and then blinks 3 times. Output over-current alarm, dis/re-connected to power to recover.
Red LED blinks 4 times, 1 second interval, then blinks 4 times. Output over-voltage alarm, dis/re-connected to power to recover.

This chart can also be found in the official charger manual (the external link, opens in the new window).

This charger is ideal for a range of applications, including electric vehicles, marine, RV, and other systems that utilize 12V LiFePO4 batteries.

It's particularly well-suited for applications where fast charging is necessary, and the high current output can significantly reduce downtime.

The batteries are charged using a standard CC/CV (Constant Current/Constant Voltage) charging algorithm, ensuring proper and safe charging.

Thus, PowerUrus 14.6V 30A E8 LiFePO4 Battery Charger is NOT suitable for 12V lead-acid batteries - after all, it is not designed with those batteries in mind...

IP66 Rating: What That Actually Means?

The IP66 rating is a designation under the International Protection Marking system, which classifies and rates the degree of protection provided against intrusion, dust, accidental contact, and water in electrical enclosures.

Here’s what each part of the IP66 rating means:

  • IP: Stands for "Ingress Protection," which is the rating system used.
  • 6 (First Digit): This indicates the level of protection against solid objects. A rating of "6" is the highest standard for solid protection, signifying that the charger is dust-tight and completely protected against any ingress of dust.
  • 6 (Second Digit): This digit describes the level of protection against liquids. A "6" in this position indicates that the charger can withstand powerful water jets from any direction without harmful effects. Typically, this means it can handle strong jets (12.5 mm nozzle) of water projected against the enclosure from any angle.

An IP66-rated device like the PowerUrus 14.6V-30A E8 LiFePO4 Battery Charger is well-suited for use in environments where it might be exposed to dust and water, making it an excellent choice for outdoor, industrial, or potentially wet conditions, enhancing its versatility and durability in challenging environments.

Recommended Charging Battery Sizes

Since the charger features 30 Amps maximum charging current, the charger is suitable for a broad range of batteries and applications.

Many LiFePO4 batteries feature a maximum charging current of around 1C, but to prolong the battery's operating lifetime, the charging current should be kept around 0.5C or less (this is the personal opinion of the author - hint: a 50+ years "young" guy with decades of experience in this field).

Thus, the PowerUrus 14.6V 30A E8 LiFePO4 Battery Charger should be used for batteries with capacities of at least 50-60Ah.

For example, if you have the PowerUrus 12V 100Ah Smart LiFePO4 Battery (Amazon link, the link opens in the new window) powering your 50-60 lbs electric trolling motor drawing 50 Amps at full throttle and you are using it at rate (per fishing trip):

  • 100% Throttle (50A): 30 minutes → requires 25Ah,
  • 50% Throttle (25A): 120 minutes → requires 50Ah.

At that rate, you need 75Ah per fishing trip, with the remaining 25Ah being a very nice safety margin.

Also, at that rate, the PowerUrus 14.6V 30A E8 LiFePO4 Battery Charger requires some ~3h to recharge the battery fully, ensuring up to 2 fishing trips per day, assuming 12h of daylight.

Note: If you are using your trolling motor mostly at 100% throttle, your trolling motor is seriously underpowered...

Similarly, the charger can be used to recharge even larger batteries - for example, a 12V 200Ah battery discharged down to 80% DoD (40Ah remaining) can be recharged in 6-7 hours, depending on the battery condition.


powerurus 14 6v 30a charger mLong Story Short: the PowerUrus 14.6V 30A E8 LiFePO4 Battery Charger is a high-quality, efficient, and reliable option for anyone looking to maximize the performance and lifespan of their LiFePO4 batteries.

Its combination of powerful output, comprehensive safety features, broad temperature range, and user-friendly design make it a valuable tool for a wide range of power management tasks.
